2/5c+4-1/5c=-9

Mathematics
1 answer:
timurjin [86]2 years ago
5 0

Answer:

c = - 65

Step-by-step explanation:

Combine like terms on the left

2/5 c - 1/5 c + 4 = - 9

1/5 c + 4 = - 9              

Subtract 4 from both sides

1/5 c = - 9 - 4

Combine like terms on the right

1/5 c = - 13

Multiply both sides by 5

5(1/5 c) = - 13 * 5

c = - 65

The difference of five and one-tenth, and half of a number is one and six-tenths. What is the number?
mario62 [17]

The number is 7 if the difference of five and one-tenth, and half of a number is one and six-tenths.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The difference between five and one-tenth, and half of a number is one and six-tenths.

Let x be the number:

= 5 1/10 - x/2 = 1 6/10

= 51/10 - x/2 = 16/10

x/2 = 51/10 - 16/10

x/2 = (51-16)/10

x/2 = 35/10

x = 7

Thus, the number is 7 if the difference of five and one-tenth, and half of a number is one and six-tenths.
